Overweight/obese people are prone to develop cardiovascular, respiratory and other chronic diseases at young age because of abnormal weight. Aerobic capacity (VO2 max) is an accepted index of cardio respiratory fitness. Decrease in VO2 max can be an early marker for altered cardiovascular physiology.
The present study was carried out with the objective of evaluating aerobic capacity in overweight young females and comparing it with that of normal weight females.
Twenty-three female subjects aged 18-20 years were enrolled in each group. Group 1 comprised overweight subjects and group 2 comprised normal weight subjects. Analysis to assess the difference in VO2 max between the groups was done by unpaired t-test.
Mean age of group 1 and 2 was 18.91 ± 0.67 years and 18.83 ± 0.78 years, respectively. Mean BMI in group 1 and 2 was 26.18 ± 1.06 kg/m(2) and 20.65 ± 1.5 kg/m(2) respectively. VO2 max in groups 1 and 2 was 34.52 ± 3.26 ml/min/kg and 37.51 ± 2.88 ml/min/kg respectively. The difference in VO2 max found in overweight girls was statistically significant with P value of 0.002.
Overweight girls had significantly reduced, cardio-respiratory fitness when compared to normal weight young females.
超重/肥胖人群由于体重异常，在年轻时容易患心血管、呼吸及其他慢性疾病。有氧能力（最大摄氧量）是公认的心肺适能指标。最大摄氧量的降低可能是心血管生理改变的早期标志。
本研究旨在评估超重年轻女性的有氧能力，并将其与正常体重女性的有氧能力进行比较。
每组招募23名年龄在18 - 20岁的女性受试者。第1组为超重受试者，第2组为正常体重受试者。通过成组t检验分析评估两组之间最大摄氧量的差异。
第1组和第2组的平均年龄分别为18.91±0.67岁和18.83±0.78岁。第1组和第2组的平均体重指数分别为26.18±1.06kg/m²和20.65±1.5kg/m²。第1组和第2组的最大摄氧量分别为34.52±3.26ml/min/kg和37.51±2.88ml/min/kg。超重女孩的最大摄氧量差异具有统计学意义，P值为0.002。
与正常体重的年轻女性相比，超重女孩的心肺适能显著降低。
